12 13 Coprolites are often used in African archaeological sites as archives for proxies like pollen, which 14 are trapped and preserved inside them. Investigating pollen taphonomy, here we aim to aid 15 interpretations of local and regional vegetation changes by assessing dietary and other pollen 16 sources of fresh hyaena scats from the Tswalu Kalahari Reserve (TKR, South Africa) and coprolite...

The Adélie penguin is the most important animal currently used for ecosystem monitoring in the Southern Ocean. The diet of this species is generally studied by visual analysis of stomach contents; or ratios of isotopes of carbon and nitrogen incorporated into the penguin from its food. There are significant limitations to the information that can be gained from these methods. We evaluated popul...

The large availability and renewable nature of lignin makes its upgrading to bioproducts particular interest for sustainable development. hydrodeoxygenation (HDO) anisole specifically represents a model reaction the conversion biofuels through removal aromatic carbon-oxygen bonds. To date, range Ni-based catalysts have been reported as highly active systems HDO anisole. However, there has subst...

Coyotes Canis latrans in urban landscapes provide important food web functions and ecological services but can also trigger human-wildlife conflict when their diet includes anthropogenic resources or domestic pets. As adaptable omnivores, coyotes adjust to environment, routinely switching among items accommodate spatial seasonal differences availability. To evaluate the coyote's potential impac...

Spotted scats (Scatophagus argus) are euryhaline fish of the family scatophagidae inhabiting Indian and western Pacific oceans including Sundarbans estuary Bangladesh having good demand as food aquarium. The present study describes nursery rearing techniques spotted to optimize stocking densities for better survival, growth production.

The development of an urban area should be followed by the arrangement adequate infrastructure. One important needs in is transportation. An increase number means transport often creates congestion, especially at intersections. timing cycles that do not lead tothe vehicles lining up but only based on a balanced division time one causes congestion. Based this background, system setting flame cyc...

In this note, we present the first reports for Hydrochoerus isthmius in northeastern coastal border of Magdalena department (Colombia). Records were based on direct evidence (Camera traps, skeletal remains, situ photographs) and indirect (scats tracks). We evidenced that species inhabits wetlands located between two national parks, Tayrona Sierra Nevada de Santa Marta.
